Glen Campbell will unveil his final studio album on June 9, six years after being diagnosed with Alzheimer’s disease.

Called “Adiós,” the album features 12 classic songs that Campbell loved, but never had the opportunity to record. Among them are “Don’t Think Twice It’s All Right,” “Everybody’s Talkin’” and title track “Adiós,” made famous by Linda Ronstadt.

The set, recorded in Nashville shortly after the music legend wrapped his 2011 “Goodbye Tour,” features guest appearances by Willie Nelson, Vince Gill and Campbell’s children, Ashley, Shannon and Cal.

“Glen’s abilities to play, sing and remember songs began to rapidly decline after his diagnosis in 2011,” Campbell’s wife, Kim Campbell, told People on Friday. “A feeling of urgency grew to get him into the studio one last time to capture what magic was left. It was now or never.”
